Tent structure foldable

ABSTRACT

This invention is a tent structure foldable, comprising a framework and a canvas covering the framework, in which the framework is structured with a plurality of horizontal bars flexible, a plurality of vertical poles detachable, and a plurality of holders bendable so that the tent structure is made to be easily unfolded for use and easily folded for safekeeping.

FIELD OF THE INVENTION

This invention relates to a tent structure foldable and particularly to a tent structure that may be easily folded for safekeeping.

BACKGROUND OF THE INVENTION

Conventionally, a general tent as shown in FIG. 13 is mainly made up with a canvas 3, two vertical poles 4 located at two openings of terminals of the canvas 3, and a horizontal bar 5 located between the two vertical poles 4, and after a rope 6 is used to bind and tense the structure at each corner outside the canvas 3, a fixing nail 7 is used as a fixture on the ground, thereby the tent being formed.

Although the canvas 3, the two vertical poles 4, the horizontal bar 5, the rope 6, and the fixing nail 7 are used to form the mentioned-above tent, they must be assembled one after another when structured and must be unfolded when detached; thus, the procedures for unfolding and taking apart the tent structure are complicated and a lager space is occupied by the tent after folded, and many persons are required to co-work to securely hold the conventional tent when assembled but a single person cannot complete the task independently. For this reason, the conventional tent formerly described is obviously inconvenient and imperfect in practical use.

SUMMARY OF THE INVENTION

This invention is mainly to make a tent structure effectively easily unfolded for use.

This invention is further to make the tent structure easily folded for safekeeping.

In order to achieve the object mentioned above, the invention is the tent structure foldable, in which it is formed with a framework and a canvas covering the framework. The framework is structured with a plurality of horizontal bars flexible, a plurality of vertical poles detachable, and a plurality of holders bendable, in which one end of each horizontal bar is located on a connection mount and the other end of that is mounted with an axle seat so that one end of each vertical poles is located on the axle seat, and the other end of that is connected to each other and thereby two ends of each holder are respectively located at two sides of the axle seat; the canvas covers the outside of the framework mentioned above. Consequently, the tent structure may be easily unfolded for use and easily folded for safekeeping.

As shown in the figures, this invention is a foldable tent structure 1 with a framework 1 and a canvas 2, and it may be easily unfolded for use and easily folded for safekeeping.

The above-mentioned framework 1 is structured with a plurality of horizontal bars 11 flexible, a plurality of vertical poles 12 detachable, and a plurality of holders 13 bendable, in which the horizontal bar 11 is made up with an inner tube 111 and a sleeve 112 between both of which an elastic element 113 is provided, the vertical pole 12 is made up with two pipes 121 and 122, two butt joints 123 and 124 of the two pipes 121 and 122 are connected with each other, an elastic element 125 is provided between the two pipes 121 and 122, the holder 13 is made up with two rods 131 and 132 connected with each other through a joint 133, the two rods 131 and 132 is actively riveted on the joint 133 through a stalk 134; also, one end of each horizontal bar 11 is located on a connection mount 14 provided with more than one rib 141 so that one end of the horizontal bar 11 is actively located on the rib 141 following a stalk 142 moving and the other end of each horizontal bar 11 is provided with an axle seat 15 for one end of each vertical pole 12 to be located on the axle seat 15 and for the other end of that to be connected to each other through a fixing element 16, two ends of each holder 13 are respectively located at two sides of the axle seat 15, and the axle seat 15 and each horizontal bar 11, each vertical pole 12, and the holder 13 are actively riveted to each other in coordination with a pivot 151.

The canvas 2 covers the outside of the framework 1 mentioned above and is fixed on the framework 1 by a plurality of fixing parts 21, a plurality of mouths 23 and an exit/entrance 22 are provided on the canvas 2, the circumference of exit/entrance 22 of the canvas 2 is provided with a chain portion 221 so that the exit/entrance 22 may be opened and closed for users to exit from and enter the canvas 2, the plurality of mouths 23 of the canvas 2 are respectively provided with a net 24, one side of the mouth 23 may be covered with a shelter 25, the circumference of the mouth 23 and shelter 25 connects through a chain portion 231 so that the mouth 23 may be opened and closed through the shelter 25. Accordingly, with the above-mentioned structure, a brand-new tent foldable is formed.

FIGS. 9 and 10 are schematic views illustrating an unfolding state of this invention. As shown in the figures, when this invention is unfolded (originally folded) for use, the user applies an upward external force to the connection mount 14 so that the horizontal bar 11 of the connection mount 14 is made to be pulled to fixing through the elastic element 113 between the inner tube 111 and the sleeve 112 and that the axle seat 15 at the other end of the horizontal bar 11 is made to be outwardly pushed to a predetermined position through the horizontal bar 11 pulled to fixing; at this time, each holder 13 on each axle seat 15 becomes straight from a bent form through the joint 133, meanwhile links with a pipe 121 of the vertical pole 12 to work together at the predetermined position, and next connects with the butt joints 123 and 124 of the two pipes 121 and 122 of the vertical pole 12, and thereby the tent structure may be made to be effectively easily unfolded for use.

FIGS. 11 and 12 are schematic views illustrating a folding state of this invention. As shown in the figures, when this invention is folded, the user applies a downward external force to the connection mount 14 so that the horizontal bar 11 of the connection mount 14 is made to be contracted through the elastic element 113 between the inner tube 111 and the sleeve 112 and that the axle seat 15 at the other end of the horizontal bar 11 is made to be inwardly pulled to a predetermined position through the horizontal bar 11 contracted; at this time, each holder 13 on each axle seat 15 becomes bent from a straight form through the joint 133 and meanwhile detached from the butt joints 123 and 124 of the two pipes 121 and 122 of the vertical pole 12, and thereby the tent structure may be made to be easily folded for safekeeping.
